Some of Chile's best surf breaks on the shore of the Atacama, the driest desert in the world. This dual-compartment daypack has an outside mesh pocket with waterproof barrier to stow a damp wetsuit or drippy waders. The main compartment includes plenty of organizers for pens, electronics, keys and phone, along with a raised, padded sleeve to protect up to a 17-inch laptop. The sleeve also holds a hydration reservoir and comes equipped with a tube port. Adjustable webbing straps take on a skateboard or bulky clothing, and two stretch pockets keep water bottles at your side. Airflow mesh on the shoulder straps and back panel prevent overheating, compression straps stabilize the load, and the sternum strap has a built-in emergency whistle. Made of a 420-denier 100% nylon oxford plain weave, with an 840-denier 100% ballistics nylon bottom. The lining is 200-denier 100% polyester. All fabrics have a Deluge® DWR (durable water repellent) finish.
